Abstract
An apparatus and a corresponding method for the iontophoretic delivery of drugs that operates only when the supply voltage is higher than a predetermined threshold is provided. The apparatus includes a current control circuit for controlling the current in an iontophoretic patch, and a supply voltage detection circuit. When a low supply voltage is detected, the current control circuit is disabled, which stops the iontophoretic current, thereby stopping the delivery of drugs.
